Jep, the file is attached, the search term is "lstlist"

The crash occurs with "syntax on". I am using same configuration with
debian squeeze, and no crash will be happen.

Ok, here is my local ~/.vimrc:

--- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< ---
" Highlighting-File auch in älteren VIMs öffnen
if version < 600
        let mysyntaxfile = "~/.vim/syntax/xpress.vim"
endif


" Highlighting einschalten
syntax on
finish

" Cursor-Tasten sollen nach Display-Zeile arbeiten, nicht nach
" echter Textzeile
noremap j gj
noremap k gk

" Absatz formatieren
map <C-j> v<S-}>gq<End>

" Line-Wrapping an Wortgrenzen und nicht hart am Zeilenende
set linebreak

runtime presentation.vimrc
--- ><8 --- ><8 --- ><8 --- ><8 --- ><8 --- ><8 --- ><8 --- ><8 ---

The local ~/.vim dir is:
.vim
├── filetype.vim
├── presentation.vimrc
├── scripts.vim
└── syntax
    ├── presentation_pclcomplete.vim
    ├── presentation_pcl.vim
    ├── presentation_sdlcomplete.vim
    ├── presentation_sdl.vim
    └── xpress.vim


The global vimrc is:

--- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< --- 8>< ---
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually
just " /usr/share/vim/vimcurrent/debian.vim) and sourced by the call
to :runtime " you can find below.  If you wish to change any of those
settings, you should " do it in this file (/etc/vim/vimrc), since
debian.vim will be overwritten " everytime an upgrade of the vim
packages is performed.  It is recommended to " make changes after
sourcing debian.vim since it alters the value of the " 'compatible'
option.

endif

" Uncomment the following to have Vim load indentation rules and plugins

Hope it helps, and thanks in advance
